Hi Sandausp, I'm not quite as blunt as _Bob, but he's right, it will not consistently win you the 20 pips you are aiming for.
Firstly, the 4 hour S & R levels on your chart will be helpful in determining short term price direction. But your plan to have so many indicators for a 1 - 5 min Chart..... it will either confuse the hell out of you or give so many conflicting signals that opportunities will be few and far between..... Limit it to 1 or 2 Indicators.. say RSI and one 8,12, 20 MA..
Use a pair with low spread ie: EURUSD, GBPUSD, AUDJPY, EURGBP.....maybe a few others.
You can add a 100 - 200 WMA to give you a little confirmation and longer view of price direction.
ALWAYS practice on a demo first, and trade it if was a real account, small lots and as little risk as possible. You will know within a few hours if the strategy will work, needs a few tweaks... or is death by 1000 cuts......
